WebGraphite Like diamond, graphite is also a giant covalent structure, with each carbon atom forming three covalent bonds, resulting in layers of hexagonal rings in carbon atoms. … WebBauxite is first crushed and mixed with sodium hydroxide. The aluminium oxide reacts with the sodium hydroxide and dissolves Al 2 O 3 (s) + 2NaOH (aq) ———-> 2NaAlO 2 (aq) + H 2 O Sodium aluminate is formed (2NaAlO 2 ). This is then heated to extract the aluminium oxide. Aluminium is extracted from aluminium oxide through electrolysis.
